I wanted to say THANKS to all that helped me and give me advice to resolve my trailer reverse backing up. I took your advice on which fuses to check on Friday. Saturday I went fishing and my partner was backing my boat down the ramp and I was standing on the ramp. When he was backing up I was totally shocked that I had reverse lights and it floored me. I guess one of those fuses you told me to check was not seated good because I changed or added nothing. I just pulled them out and checked them. I sure hope it works again this weekend. Thanks again for all your help.
